To all/whom t may concern',

B e it known that I, HOWARD T. CHINN, a citizen of the United States,residing at Florin, in the county of Sacramento and is a justableto'dispose the rest in dilerent positlons, novel means being providedholding the guard in any position to which it may have been adjusted.

It is' within the province of the discloszo ure to improve generally andto enhance the utility of devices of 4that typeI to which theapplication a pertains.

With the a ove and other objects in view, which will appear as thedescription proceeds, the invention resides in the comblnation andarrangement of parte and in the details ofconstruction hereinafterdescribed and claimed, it being understood that, within the scope ofwhat is claimed, changes in a0 the precise embodiment of the inventionshown can be made without departing from the spirit of the invention.

In the accompanyin drawings .Figure 1 shows in side elevation, a deviceconstructed in accordance with the invention; Figure 2 is lalongitudinal section wherein parts are broken away; Fi re 3V is anelevation wherein parts are roken located in the recess 35 formed m thebearing 29./ The beveled gear 34 has a neck 50 awa T e .device formingthe subject matter of this application includes a handle 1 comprising asocket 2 and any desired number.

of sections 3 and 4, the construction being such that the handle ma beof an desired length. The section 3 as a soc et 5 receiving the section4, the section 3 bein received in the socket 2, the parts being eldtogether by pin and ba onetslot connec- A tions 6', or in any desireway, so that the handle may bev lengthened or shortened at the will ofanoperator, thereby enablin the saw, Vhereinafter alluded to, to be u ontrees of different hei hts .and under other conditionswhich wi suggestthemselves to the user. Y

A bearing 7 is mounted m the upper end of the handle section 4 and hasan outstanding flange 8 the bearing being vheld in the section 4 by apin 9 mounted in the said section. A collar l() is journaled in thebearing 7 and is threaded or held otherwise, as at 11 on the stub shaft12 provided at its upper end with a beveled gear 14. Balls 15 or otheranti-friction elements are intertnosedv between the beveled gear 14 andthe earing 7. The balls 15 are interposed between the bearing 7 and thecollar 10. The

shaft 12 is detacliably connected at 17 with a shaft 18 provided at itslower end with a collar 19 having an extension 20 journaled -in abearing 21 carried by the lower end of the handle section 4,anti-friction balls 60 v being .interposed between the collar" 19 andthe bearing 21. The member 20 is detachablyconnected at 22 with ashaft23 journaled in a bearing 24 mounted in the u per end ofthe handlesection 4. A iexible s aft 25 extends into the socket 2 and may beconnected in any suitable way with the shaft 23.

The upper end of the handle section 4 abuts against the ange 8 on 'thebearing? and the lian e 8 extends over a collar 26 mounted on t e handlesection 4 yand includin adepending arm 27 extended downwardly r alongthe handle section 4, the arm 27 beino` provided at its lower end withan u wardly extended semi-circular gulde 28. T e numeral 29 denotes'atransverse bearing having a neck 30 surrounding the bearing 7 and heldthereon by a pin 31 or otherwise. A shaft 32 is held in the bearing 29by a nut 33. A beveled gear 34meshes with the'beveled gear 14 and isjournaled on the shaft 32, the beveled gears 34 and 14 belng providedwith an upstandin-g ange 36. A cap 37 is threaded on the neck 50 of thebeveled gear 34. A saw 38 is mounted on the neck and is bound avainstthe ane 36 by the cap 37 so that when the bevele gear 34 is rotated, thesaw will be rotated also. vBalls 39 are located in the neck 50 of thebeveled gear 34 and in the cajl 37 and cooperate with the outer end of te shaft 32 to support the beveled. gear; the cap and the sawantifrictionall for rotation.

The numera 40 marks a guard which 1s 1n the form of an approximatelysemi-circular portion of the flange 36 of the beveled gear 34.

Adjacent to its lower end, the guard 40 has an angularly disposedoutstanding rest 41.

rAt lits rear side, the guard 40 carries an approximately semi-circularflange '42 which overhangs the guard 28 and steadies and' holds theguard in place for swinging movement in a direction at right angles t'othe Ior the like is placed against the rest 441 and is severed bytheaction of the saw 38, rotation being imparted to the saw, fromtheshaft-'25-23-18-12 by Way of the beveled pinions 14 ,and 34. Theprojection 45 on the latch 44'may bedisengaged from the opening 43 inthe' guard 40 and, then the guard may be shifted circumferentially, todispose the'rest 41 in any desired position, the projection 45 onthelatch 44 being again enga ed with one of the openings 43 in the guarThus, the rest 41 may be shifted so that it will always .be in a properposition to cooperate with the branch or the like which is to be cut offby the saw 38.

What is claimed is 1. In a device of the class described, a handle; adriven shaft carried by the handle; a'lxed shaft carried by the handleand dis- 5 posed at right anglesl to the driven shaft;

intel-meshing beveled pinions, one of which is journaled on the fixedshaft, thel other of saw; a guard mounted to swing on the handle in aplane parallel to the sawand provided with a projecting rest, the guardhaving"a plurality of openings; and a latch onv the handle, the latchbeingl adapted to be 'engaged in any of the openings of the guard.

3. In a device of the class described, a handle; a saw journaled forrotation on the handle; means for rotating the saw;y an

arcuate guide projecting from the handle and slidably supported on theguide; a

guard mounted to rook on the handle; the

guard being equipped with a projecting rest defining an angle with theperi hery of the saw; and means for holding t e guard in adj ustedVpositions. v

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
